Factory Description
Specialized’s Fatboy Trail has a hearty appetite for any kind of terrain you can serve up. This trail-eating champ is built around a lightweight aluminum frame and RockShox Bluto RL fork. The real stomach of this monster takes the form of the 4.6-inch Ground Control tires that give you low-pressure grip on any terrain. They’re mated to wide aluminum rims that give you stability even on the loosest terrain. While you’re eyeing new and offbeat places to roll your Fatboy, you can count on the efficient one-by SRAM X7 drivetrain to get you there quickly. When it’s time to slow it all down and take in the scenery, Tektro Gemini brakes are on the case. Sand? Snow? Mud? The Fatboy has an appetite for it all, so feed the beast!
